WARNING
ARC WELDING CAN BE HAZARDOUS. PROTECT YOURSELF AND OTHERS FROM
POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN AWAY. PACEMAKER
WEARERS SHOULD CONSULT WITH THEIR DOCTOR BEFORE OPERATING.
BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR
PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
ELECTRIC AND
MAGNETIC FIELDS
may be dangerous.
1.a Electric current flowing through any conductor
causes localized Electric and Magnetic Field
(EMF). Welding current creates EMF fields
around welding cables and welding machines.
1.b EMF fields may interfere with some pacemakers,
and welders having a pacemaker should consult
their physican before welding.
1.c All welders should use the following procedures
in order to minimize exposure to EMF fields from
the welding circuit:
1.c.1 Route the electrode and work cables
together – Secure them with tape when
possible.
1.c.2 Never coil the electrode lead around your
body.
1.c.3 Do not place your body between the
electrode and work cables. If the electrode
cable is on your right side, the work cable
should also be on your right side.
1.c.4 Connect the work cable to the workpiece
as close as possible to the area being
welded.
ARC RAYS can burn.
2.a Use a shield with the proper filter and cover
plates to protect your eyes from sparks and the
rays of the arc. Headshield and filter lens should
conform to ANSI Z87. I standards.
2.b Use suitable clothing made from durable flameresistant material to protect your skin and that of
your helpers from the arc rays.
2.c Protect other nearby personnel with suitable,
non-flammable screening and/or warn them not
to watch the arc nor expose themselves to the
arc rays or to hot spatter or metal.
ELECTRIC SHOCK can
kill.
3.a The electrode and work (or ground) circuits are
electrically “hot” when the welder is on. Do not
touch these “hot” parts with your bare skin or wet
clothing. Wear dry, hole-free gloves to insulate
hand.
3.b Insulate yourself from work and ground using dry
insulation. Make certain the insulation is large
enough to cover your full area of physical contact
with work and ground.
In addition to the normal safety precautions,
if welding must be performed under
electrically hazardous conditions (in damp
locations or while wearing wet clothing; on
metal structures such as floors, grating or
scaffolds; when in cramped positions such
as sitting, kneeling or lying, if there is a high
risk of unavoidable or accidental contact with
the workpiece or ground) use the following
equipment:
 Semiautomatic DC Constant Voltage (Wire)
Welder.
 DC Menual (Stick) Welder.
 AC Welder with Reduced Voltage Control.
3.c In semiautomatic or automatic wire welding, the
electrode, electrode reel, welding head, nozzle or
semiautomatic welding gun are also electrically
“hot”.
3.d Always be sure the work cable makes a good
electrical connection with the metal being
welded. The connection should be as close as
possible to the area being welded.
3.e Ground the work or metal to be welded to a good
electrical (earth) ground.
3.f Maintain the electrode holder, work clamp,
welding cable and welding machine in good, safe
operating condition. Replace damaged
insulation.
3.g Never dip the electrode in water for cooling.
3.h Never simultaneously touch electrically “hot”
parts of electrode holder to two welders because
voltage between the two can be total of the open
circuit voltage of both welders.

SAFETY
FUMES AND GASES
can be dangerous.
4.a Welding may produce fumes and gases
hazardous to health. Avoid breathing these
fumes and gases. When welding, keep your
head out of fume. Use enough ventilation and/or
exhaust at the arc to keep fumes and gases
away from the breathing zone. When welding
with electrodes which require special
ventilation such as stainless or hard facing
(see instructions on container or MSDS) or on
lead or cadmium plated steel and other
metals or coatings which produce highly
toxic fumes, keep exposure as low as
possible and below Threshold Limit Values
(TLV) using local exhaust or mechanical
ventilation. In confined spaces or in some
circumstances, outdoors, a respirator may be
required. Additional precautions are also
required when welding on galvanized steel.
4.b Do not weld in locations near chlorinated
hydrocarbon vapors coming from degreasing,
cleaning or spraying operations. The heat and
rays or the arc can react with solvent vapors to
form phosgene, a highly toxic gas, and other
irritating products.
WELDING SPARKS
can cause fire or
explosion.
6.a Remove fire hazards from the welding area. If
this is not possible, cover them to prevent the
welding sparks from starting a fire. Remember
that welding sparks and hot materials from
welding can easily go through small cracks and
openings to adjacent areas. Avoid welding near
hydraulic lines. Have a fire extinguisher readily
available.
6.b When not welding, make certain no part of the
electrode circuit is touching the work or ground.
Accidental contact can cause overheating and
create a fire hazard.
6.c Do not heat, cut or weld tanks, drums or
containers until the proper steps have been
taken to insure that such procedures will not
cause flammable or toxic vapors from subtances
inside. They can cause an explosion even
though they have been “cleaned”.
6.d Sparks and spatter are thrown from the welding
arc. Wear oil free protective garments such as
leather gloves, heavy shirt, cuffless trouses, high
shoes and a cap over your hair.
4.c Shielding gases used for arc welding can
displace air and cause injury or death. Always
use enough ventilation, especially in confined
areas, to insure breathing air is safe.
4.d Read and understand the menufacturer’s
instructions for this equipment and the
consumables to be used, including the material
safety data sheet (MSDS) and follow your
employer’s safety practices. MSDS forms are
available from your welding distributor or from
the menufacturer.
FOR ELECTRICALLY
powered equipment.
5.a Turn off input power using the disconnect switch
at the fuse box before working on the equipment.
5.b Install equipment in accordance with the national
standard, all local standards and the
menufacturer’s recommendations.
5.c Ground the equipment in accordance with the
national standards and the menufacturer’s
recommendations.
ii
CYLINDER may
explode if damaged.
7.a Use only compressed gas cylinders containing
the correct shielding gas for the process used
and properly operating regulators designed for
the gas and pressure used. All hoses, fittings,
etc. should be suitable for the application and
maintained in good condition.
7.b Always keep cylinders in an upright position
securely chained to an undercarriage or fixed
support.
7.c Cylinder should be located:
 Away from areas where they may be struck or
subjected to physical damage.
 A safe distance from arc welding or cutting
operations and any other source of heat,
sparks, or flame.
7.d Never allow the electrode, electrode holder or
any other electrically “hot” parts to touch a
cylinder.
7.e Keep your head and face away from the cylinder
valve outlet when opening the cylinder valve.
7.f Valve protection caps should always be in place
and hand tight except when the cylinder is in use
or connected for use.

connection is adequate for normal operation of the
machine. Refer to the Technical Specifications at the
beginning of this Installation section for recommended
fuse and wire sizes. Fuse the input circuit with the
recommended super lug fuse or delay type breakers.
Using fuses or circuit breakers smaller than
recommended may result in “nuisance” shut-offs from
welder inrush currents, even if the machine is not being
used at high currents.
SELECT SUITABLE LOCATION
This power source should not be subjected to falling
water, nor should any parts of it be submerged in water.
Doing so may cause improper operation as well as pose
a safety hazard. The best practice is to keep the machine
in a dry, sheltered area.
FIGURE A.1
CAUTION
The bottom of machine must always be placed on a
firm, secure, level surface. There is a danger of the
machine toppling over if this precaution is not taken.
Place the welder where clean cooling air can freely
circulate in through the back louvers and out through the
case sides. Water,dirt, dust or any foreign material that
can be drawn into the welder should be kept to a
minimum. Failure to observe these precautions can result
in excessive operating temperatures and nuisance
shutdowns.
®
Locate the INVERTEC machine away from radio
controlled machinery. Normal operation of the welder
may adversely affect the operation of RF controlled
equipment, which may result in bodily injury or damage to
the equipment.
INPUT POWER AND GROUNDING
CONNECTION
WARNING
Only a qualified electrician should connect the input
leads to the INVERTEC®. Connections should be
made in accordance with the connection diagram.
Failure to do so may result in bodily injury or death.
Open the input box on the rear of the case. Use a threephase supply line, the three live wires should go through
the three holes of the input wire holder and be securely
clamped and fixed. Connect L1, L2, L3 and ground
according to the Input Supply Connection Diagram decal,
CABLECONNECTIONS
Connect electrode and work leads with sufficient size
between the proper output studs on the power source
and the electrode or the work. Be sure the connection to
the work makes tight metal to metal electrical contact.
Poor work lead connections can result in poor welding
performance.
To avoid interference problems with other equipment
and to achieve the best possible operation, route all
cables directly to the electrode and the work. Avoid
excessive lengths and do not coil excess cable.
Cable sizes are increased for greater lengths primarily for
the purpose of minimizing voltage drop in the cable.
Minimum work and electrode cable sizes are as follows:

Release the TIG torch trigger. The machine will now
decrease the output current at downslope time, until
the Crater current is reached and the output of the
machine is turned OFF. The gas valve will remain
open to continue the flow of the shielding gas till post
flow time is over.
The new parameter value is automatically saved.
TIG Trigger Sequences
TIG welding can be done in either 2-step or 4-step mode.
The specific sequences of operation for the trigger modes
are explained below.
Symbols used:
Torch Button
Output Current
Gas Pre-flow
As shown above, it is possible to press and hold the TIG
torch trigger during downslope to quickly enter into Crater
current mode. When the TIG torch trigger is released, (if
release time is within downslope, then output will remain
crater current until downslope time is over) the output will
turn OFF and the Postflow time will start.
